I like the sounds of this! if it works on PSUs GFX etc then it should take the industry by storm
if the 'liquid metal' that they're using is mercury, they are going to fall foul of RoHS and WEEE, which will make it very difficult to be able to sell it, not to mention the fact that if it were to leak you'd get mercury poisoning
Could potentially be rubidium, francium, caesium or gallium.
rubidium, francium and ceasium are too reactive, and explode upon contact with water, ruling those out, and if gallium is used, if it gets too cold it expands when it freezes and this would break the container
I suspect its none of the above due to the extreemly hazardous nature or high cost of that. My guess is that it would be some form of compound suspension ( like a ferrofluid ) , but thats off the top of my head.
Where is it transfering the heat to? From my understanding the "liquid metal" is just going around in circles keeping the heat within the system?
Its being released as it passes the fins.
its being used in the same way as a heatpipe, but its just much better at moving heat than a heatpipe. so its moving heat into the metal fins and then a fan will probably be attached to move the heat away
What about cost of this very interesting yet new technology.
Will it be cheaper than a regular basic water set up than you can buy??? Will it still require a fan to push heat away!
Just thought I should pop in to emphasize "the worlds first commercially available liquid metal based CPU cooler". Liquid metal cooling for CPUs is not a new technology, this is just the first time it has been offered to the commercial home user market. Liquid metal cooling has been available for mission-critical server applications for years, using a mix of gallium & some other stuff (indium I think?) pumped around the loop with a magnetohydrodynamic thruster. The one I remember seeing on eBay a couple years back for Xeons resembled a normal water cooling loop more closely, with a separate radiator/fan, pump, CPU block & tubing, rather than an all-in-one tower unit like this one.
There have also been previous promises of consumer-grade liquid metal cooling before, such as Sapphire's Radeon Blizzard X850XTPE.

et voila :)
used instead of mercury in modern thermometers,
I can't imagine it could operate without a fan. If it draws heat from the CPU more efficiently, it's just going to dump it to the fins faster, so it'll still need transferring away from the fins.Quote:

hmm does sound interesting, need to see some figures soon though, ie price n temps.

I think that its going to be contending with mid to high end water cooling in both price and performance.
